The iPhone Case That Doubles As a Stun Gun

We've seen smartphone cases that pull double duty, from flashlights to flasks, snacks to vibrators. But this one may just top them all.

A new iPhone case doesn't just protect your cell, it protects you, too. Called The Yellow Jacket, the case is wired to zap an attacker with 650,000 volts in less than two seconds. (Zowya!) There's also a safety switch to prevent it from accidentally stunning you every time reach for your phone.

We're not exactly sure how legal it is to carry a phone that doubles as a stun gun, but we'd definitely feel more secure having this gadget in our purse the next time we find ourselves going down a dark alley. It's one of those things we wish we didn't feel like we needed in order to feel safe walking around at night—like self-defense classes—but would be glad to have handy just in case.
